Re-filing https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=249326 as a kernel bug. Both 13-CURRENT and 12-STABLE can now not load vboxdrv (the VirtualBox kernel driver) because it panics on kldload.

Details and backtrace in that other bug. Since vbox doesn't have a maintainer, I can't tell whether the fix is to be on the kernel side (more resilient) or the driver side (the driver API has changed, deal with it). In either case it needs some comment from kernel peeps.

Any reason we cant re-classify bug 249326 ?

No, there isn't. I'm not used to kernel-crash reporting though, and am not sure what to do with a "here is a 100% reproducible, user-facing, kernel panic that has been MFH'ed".

The patch posted for the virtualbox port in bug 249326 is sufficient in my testing.  No kernel changes are required.  I'm inclined to think that the stable/12 kernel revision which triggered the problem should be reverted, but the virtualbox-ose-kmod patch should be applied regardless.
